TYPOGRAPHICAL MACHINE.

Application filed July 17, 1923.

Serial No. 652,168.

(GRANTED UNDER THE ACT OF MARCH 3, 1883; 22 STAT. L. 625.)

To all whom it may concern:

Be it known that I, JOHN P. MURRAY, a citizen of the United States, andresident of lVashington, in the District of Columbia, have inventedcertain new and useful Improvements in Typographical Machines, of whichthe following is a specification.

The invention described herein may be. used by the Government of theUnited States or any of its officers or employees, or by any otherperson in the United States in the prosecution of work for theGovernment, without the payment of any royalty thereon.

This invention is an improvement in typographical machines designed moreparticularly for printing matter where considerable space is desiredbetween the lines of reading, such as legislative documents, althoughits use is not limited to such documents.

In the printing of some classes of documents, such as bills introducedinto the Congress of the United States, it is desirous that the lines ofprinted matter be spaced relative to each other to permit of notationsor the insertion of amendatory matter to the printed text. Furthermore,after a bill or resolution shall have been introduced into thelegislative body, it is desirous that printed copies thereof beavailable as soon as possible. For that reason the subject-matter ofsuch documents is usually set into type by type-setting machines, suchfor example as the well known linotype machines wherein the readingmatter is cast in separate lines as distinguished from single letters orin large cast forms.

In practice, after the subject-matter has been set into type it hasheretofore been necessary to have the printer manually insert spacingelements or leads between the lines of type and thereafter take proofcopies before the matter is finally printed.

The invention aims to quickly set into type the subject-matter to beprinted and to promptly produce the printed .COPIQS by forming on themetal slug or line of type spacing elements of the width required 1n theform. The new line of type thus produced effects a saving in the weightof the form and also a saving in the time and labor of the printer whowas formerly required to separately handle each spacing element or leadto be placed between the lines of type.

In accomplishing this new result the invention comprises the method andmeans whereby a cast metal element forming a line of type may beprovided with a spacing element integral therewith serving as a means toproduce lines of printed matter which may be variously spaced relativeto each other, the spacing between the lines of printed matter beingdetermined by the rib on the slug of type, the depth of the rib on theslug depending of course upon the depth of the recesses in the mold, andthis is determined by the space desired between the lines of printedmatter.

To enable those skilled in the art to more fully understand theinvention, a practical embodiment of the mold elements and of theproduct is illustrated in the accompanying drawings, wherein- Figure 1is a front elevation of the mold with the usual elevator jaw inoperative position thereon.

Figure 2 is a similar View of the mold with the elevator jaw removed anddisclosing the depth of the recesses to form the spacing ribs on theslug or line of type.

Figure 3 is a rear elevation of the mold shown in Figure 2.

Figure 4: is a top plan view of the base or fixed section of the. moldshowing the removable spacing blocks partly advanced.

Figure 5 is a bottom plan View of the mold cap or removable sectiondisclosing the spacing rib recesses formed therein.

Figure 6 is an end view of the mold looking at the left end asillustrated in Figure 2.v

Figure 7 is a rear elevation of the elevator jaw, the front view ofwhich is illustrated in the assembly view of Figure 1.

Figure 8 is a sectional view through the elevator jaw of Figure 7.

Figure 9 is a perspective View of one of the spacing blocks to mount,the removable web-forming member of the. mold.

Figure 10 is a front elevation of a line of type as produced by themold, the illustration disclosing the printing face of the slug of typeand a plurality of ribs in rear of the printing face.

Figure 11 is a plan view of the rib-formed face of the slug of type ofFigure 10.

Figure 12 is a front elevation of the printing face of the slug of typeas it would parts of the machine containing the changes necessary areillustrated in the accompanying drawings. The usualmold is shown inFigures 1, 2 and 3, wherein is illustrated the fixed element 1 and themold cap or removable section 2. The fixed element 1 is provided withthe usual liner blocks 3 slidably mounted thereon, but in carrying outthe invention is has been found desirable to provide these liner blockswith a recess 4 to receive an extension 5 which has been added to theusual elevator jaw 6.

The mold cap or removable section 2 of the mold is provided with aplurality of mold recesses 7 opening into the usual mold space 8 whichproduces the slug or line of type. These recesses 7 may he made ofvarying depth on separate mold caps 2 to provide ribs of the desiredlength to correspond to the width or depth of the lead or separatespacing element which these ribs replace and serve to produce a slug orline of type having spacing ribs integral therewith as shown in Figures10, 11 and 13. If desired, the removable section or mold cap 2 may beset back as at 9 to facilitate the mounting of the elevator jaw 6 andits extension 5 on the mold.

The matrices M now used in printing legislative documents such as billsand resolutions before the Congress of the United States, are providedwith two dies, one to form the ordinary printed letter as indisated at22 in Figure 12, and the other die to form a letter with the addition ofa horizontal line through the same as shown at 23 in Figure 12. Thedeformed letters 23 produce words with a line drawn through them toindicate the deletion of such words in the text. If a slug is cast withthe mold and elevator aw 6 constructed as ordinarily used, the slugwould have the two printing faces as disclosed in Figure 12.Accordingly, the elevator jaw 6 is provided with an extension 5 (seeFig. 6) designed to block oll one or the other, 22 or 23, of these linesof printing}; face and to produce a deformed such as is shown at 14 inFigures 10, 11 and 13. Moreover, the mold cap 2 may be so constructedthat the slug or line of type 15 will have a broad printing web 24, athinner narrow body 25, and the spacing ribs 15 integral with theprinting web and body.- The saving of metal in the body or slug lightensthe weight of the slug so that 1t, with the addition of its ribs 15, isof substantially the same weight or possibly but slightly in excess ofthe weight of an ordinary slug without the spacing ribs 15.

T his saving in weight is found of advantage in assembling a series ofribbed slugs into a form where the spacing ribs integral with the slugssave the weight of the leads formerly used. Besides, the time of theoperator is saved in that no type leads are now necessary to be insertedby hand as was formerly, to produce the spaced relation be tween thelines of printed matter.

it will be observed that the new slug of type is formed by flowingmolten type metal through the mold and the recesses 7 of the mold cap 2into contact with a single type face of a plurality of matricespresented to the mold.

Having thus described my invention, what l claim as new is 1.
